Description

In the present invention, the winding of the winding material by winding is performed by an arbitrary winding pattern, and this winding can be performed with or without a sleeve, so that the spool can be wound only or by winding only. With respect to winders that may have windings and sleeves.

The winder is used to wind the winding material, preferably in the form of "technical yarn". This is a thread or tape winding material, which is
-Flexibly formed and / or-formed as a single filament or multifilament (eg, a single filament from 12,000 or more to 300.000) and / or -100 km or more (especially 200 km or more, It has a length wound into a roll (from 300 km to 600 km) and / or a weight / length (so-called "titer") in the range of -10.000 den to 20.000 den [g / 9.000 m] (so-called "titer"). For example, it has 12.000 den to 16.000 den) and / or is wound as a horizontal winding and / or-is wound as a horizontal winding and / or without support at the end side of the drum disc. -Win at a spool speed of at least 10 m / min (preferably 30 m / min or higher or 50 m / min or higher).

General-purpose winders are known, for example, from International Publication No. 03/099695. In this winder, two take-up spindles are rotatably supported by a rotatable turret. The rotation of the turret allows the spindles to be alternately moved to the take-up and replacement positions, the spindle can be coupled to the drive at the take-up position, and the take-up material is taken up at the take-up position. Be done. A thread guide unit is pivotally supported on the frame of the winder via a swivel arm, and a pressing roller is rotatably supported facing the thread guide unit. The yarn guide unit is pressed against the outer peripheral surface of the spool wound on the spindle at the winding position via the pressing roller. The thread guide unit comprises a traverse thread guide. The traverse thread guide is driven by the traverse motion. Here the traverse yarn guide performs a traverse motion, the stroke of which essentially corresponds to the laying width of the take-up material, i.e. the axial length of the winding (eg it is between the traverse yarn guide and the deposit point). It goes through the drag path and can lead to a reduction in the laying width for the stroke), and it is oriented parallel to the longitudinal axis and / or the axis of rotation of the spindle. The rotational movement of the spindle or spool on one side and the traverse movement of the traverse yarn guide on the other side are adjusted relative to each other by appropriate control, resulting in a winding pattern as set. The take-up material reaches the traverse yarn guide directly from the head yarn guide supported by the frame of the winder, which is formed here as the head yarn guide roller, thereby reaching the outer peripheral surface of the winding via the pressing roller. It will be laid. As a result of the traverse motion of the traverse yarn guide, the take-up material travels from the head yarn guide to the traverse yarn guide in the distribution triangle. Its length is related to the distance from the traverse thread guide of the head thread guide located at the apex of the distribution triangle, in which the traverse angle changes with traverse motion within the total traverse angle α. Increasing the diameter of the winding changes the distance of the pressing roller from the longitudinal axis and / or the axis of rotation of the spindle, thereby causing compensatory movement of the swivel arm to rotate while the thread guide unit is held.

A more general purpose winder is sold by the applicant under the name "SAHM830XE" (www.sahmwinder.de/produkte/sahm-carbon-fiber-winders/sahm-830xe.html, Search Date: 8/2018) See May 22). This winder does not have a turret, but has a single spindle with a longitudinal axis and / or a rotating axis fixed to the frame of the winder. In this winder, the thread guide unit is not supported by a swivel arm that is rotatably supported with respect to the frame. Rather, the compensatory movement of the yarn guide unit is caused by an increase in the diameter of the winding as the yarn guide unit is horizontally and translationally guided to the frame of the winder. Again, the take-up material reaches the traverse yarn guide of the yarn guide unit directly from the head yarn guide roller supported by the frame of the winder.

European Patent No. 1656317 is first implemented with a thread guide unit carrying an overflow bracket, which is rotatably supported by a swivel arm, whereby the take-up material is deflected between the head thread guide and the traverse thread guide. The form will be described. In this embodiment, a dancer roller is placed in front of the head yarn guide, which can be deflected against the pressurization of the spring to keep the tension in the take-up material as constant as possible. Useful. When a dancer roller shift occurs due to a change in tension in the take-up material, this shift is controlled or controlled to maintain a given tension in the take-up material and provide a constant equilibrium position for the dancer roller. It can be used for adjustment and can also be used for adjusting the rotation speed of the drive device. With respect to this known prior art, European Patent No. 1656317 states that during traverse motion, the length of the take-up material within the distribution triangle changes with the high frequency corresponding to the high frequency traverse motion, which in the take-up material. Explains that it leads to undesired changes in tension. In some cases, this cannot be corrected by adjusting the rotation speed of the dancer rollers and the spindle drive device. In order to keep the change in yarn length within the distribution triangle as small as possible, the distance of the head yarn guide from the yarn guide unit is increased, which increases the installation space requirement of the winder. Therefore, according to European Patent No. 1656317, as the diameter of the winding increases, the swivel arm holding the thread guide unit also rotates in relation to the turning angle of the swivel arm. It describes the finding that the length of the take material varies between the head yarn guide and the yarn guide unit, i.e., the length of the distribution triangle. This should also cause a change in tension in the take-up material, so that the take-up material is laid on the roll with different tension. If the tension of the take-up material changes between the end of the spool and the center of the spool, European Patent No. 1656317 allows the take-up material to be released from the end of the winding and wound around the core of the spool. However, it can lead to a machine stop, or even if the spool is used later, the machine may stop during rewinding or it may lead to machine damage. European Patent No. 1656317 proposes to provide additional thread support means by a retrofit traverse thread guide between the head thread guide and the deflection bracket. It is held by the deflection bracket at the greatest possible distance from the traverse thread guide via the cantilever arm. In this case, the vertices of the distribution triangle are set by additional thread support means rather than by the head thread guide. Since the thread supporting means swivels with the swivel of the swivel arm and the thread guide unit, the length of the distribution triangle does not change with increasing diameter of the winding. The inlet angle of the take-up material does not change between the head yarn guide and the additional yarn support means and is independent of traverse motion. Thus, the undesired effect of the change in winding diameter on the length of the distribution triangle is avoided by using thread support means. European Patent No. 1656317 to avoid changes in the length of the take-up material in the distribution triangle and thereby changes in traverse motion and tension in the take-up material associated with the traverse angle in the distribution triangle that changes with the traverse motion. The specification complementarily proposes the use of curved overflow brackets. It is supported by a yarn guide unit and performs additional deflection of the take-up material between the traverse yarn guide and additional yarn support means, to a degree of traverse angle in the distribution triangle that changes with traverse motion. Changes in relation. The contour of the overflow bracket is adapted so that the length of the take-up material between the thread support means and the traverse thread guide does not change regardless of the position of the traverse thread guide, i.e., regardless of the traverse angle within the distribution triangle. For this purpose, the overflow bracket is used to create a stronger deflection of the take-up material when the traverse yarn guide is in the center than when the traverse yarn guide is in the end region. European Patent No. 1656317 further states that an additional roller is supported by the thread guide unit via a cantilever arm in which the DMS is placed, and this additional roller is placed in front of the thread support means. The embodiments are also disclosed. In order to keep the mass and design size of the thread guide unit small, the length of the cantilever arm on which the thread support means is supported is severely restricted, which also shortens the length of the distribution triangle. This also has the disadvantage that the traverse motion changes the tension in the take-up material to an undesired degree or requires the use of a curved overflow bracket, which can damage the take-up material. It can be undesirable as a result of additional deflection.

The winder is also sold by the applicant under the name "Carbon Star 850XE" (see www.sahmwinder.de/produkte/sahm-carbon-fiber-winders/carbonstar-ii.html; Search Date: 2018 August 22). There, the yarn guide unit with the traverse yarn guide is linearly moved towards the head yarn guide by compensatory motion as a result of the increased winding diameter. In this way, the compensatory movement does not change the inlet angle, the angle at which the take-up material leaves the head yarn guide, and the angle at which the take-up material enters the yarn guide unit. However, in this embodiment, the compensatory movement shortens the length of the distribution triangle, which results in the compensatory movement increasing the total traverse angle α of the distribution triangle, thereby the necessary deflection of the take-up material by the traverse yarn guide. The degree of is also expanded, which is not desirable.

In addition, the applicant sells a winder named "SAHM 880XE" (see www.sahmwinder.de/produkte/sahm-carbon-fiber-winders/sahm-880xe.html; Search Date: August 2018 22nd of March). Here, a thread guide unit with a traverse thread guide is fixedly placed on the frame of the winder and the spindle is displaced with the spool formed on it for compensatory movement. However, this embodiment requires a very stable structure, especially for heavy spools, so this embodiment is preferably used for light spools weighing 20 kg or less.

From this point of view, we are proposing an improved winder.

The subject of the present invention is solved by the characteristics of the independent claims according to the present invention. Further preferred embodiments of the invention are described in the dependent claims.

The winder of the present invention has a frame that can be formed as a base plate, frame or housing. The winder may or may not have, for example, a rotatable spindle to provide rotational movement of the spool during winding, especially because the drive of the spool causes rotational movement. It can be done via a drive device of the spool body or a friction drive device that interacts with the outer peripheral surface of the winding. The present invention includes not only one spindle but also an embodiment in which at least two spindles are provided in the winder. Here, it is also possible that at least two spindles are held in the turret (see the prior art mentioned at the beginning, European Patent Application Publication No. 1507730).

The winder of the present invention includes a yarn guide unit. The thread guide unit has a traverse thread guide that is driven while traversing. The yarn guide unit includes a pressing means that is pressed against the outer peripheral surface of the winding wound on the spindle. The pressing means is preferably a pressing roller rotatably supported by the substrate of the yarn guide unit. Such pressing rollers can be used for the winding support of the yarn guide unit. It is also possible to additionally guarantee the laying of the winding material on the outer peripheral surface of the winding material via the pressing roller. In addition, it is also possible to compress the winding in response to pressure applied to the outer peripheral surface of the winding via a pressing roller, whereby this can be formed harder and / or within the same diameter of the winding. In addition, another length of winding material can be stockpiled. It is also possible for the pressing roller to exert a variable pressurizing force on the outer peripheral surface of the winding throughout the winding process. In addition, the control or adjustment of the pressure applied to the outer peripheral surface of the winding of the pressing roller is such that the winding does not swell due to excessive pressure or marking is made on the winding material at the intersection of the windings. It is possible to be done. During the winding process, the yarn guide unit (and thereby the traverse yarn guide) can be moved by compensatory movement against the spindle in response to the increased diameter of the winding, which is guaranteed by the support of the pressing means on the outer peripheral surface of the winding. To.

The winder has a head yarn guide. This head thread guide is placed in front of the traverse thread guide in the thread path. The head yarn guide is placed, held and / or guided on the frame at a distance from the yarn guide unit. The take-up material reaches the yarn guide unit directly from the head yarn guide without the take-up material deflecting the take-up material on the way between the head yarn guide and the yarn guide unit. The head thread guide sets the vertices of the distribution triangle.

In the prior art, the head yarn guide had to be fixedly placed on the frame of the winder, while at the same time measures against the effects of the winding material path and deflection, especially in the context of compensatory movement. On the other hand, it emerged from the prejudice that it must be taken in relation to the traverse movement within the distribution triangle, outside the area of the thread guide unit.

For the first time (alternatively or cumulatively to these known measures taken in the area of yarn guide units), the present invention allows the head yarn guides to be movably held and guided by the frame of the winder. suggest. Here, within the framework of the present invention, the movement of the head yarn guide is carried out in relation to the compensatory movement which carries out the yarn guide unit with the change in the diameter of the winding. Here, the movement of the head yarn guide occurs so that the action of the compensatory movement on the path of the take-up material between the head yarn guide and the traverse yarn guide is at least suppressed. In particular, in the present invention, the exit angle of the take-up material from the head thread guide and / or the deflection angle of the take-up material in the region of the head thread guide, and / or the entrance angle of the take-up material to the thread guide unit. , And / or changes in deflection angle in the area of the yarn guide unit of the take-up material, especially in the area of the traverse yarn guide, are suppressed or completely eliminated in relation to the compensatory motion.

Basically any movement of the head thread guide can occur. To give some non-limiting examples of the present invention, the head yarn guides can be guided via translational guides, curved guides or arc guides facing the frame. This variant is used both when the thread guide unit is guided translationally with respect to the frame and also when the thread guide unit is rotatably guided with respect to the frame, for example via a swivel arm. Can be done. Here, the movement of the head yarn guide preferably corresponds to or approximates the compensatory movement of the yarn guide unit in terms of direction and / or quantity. In a particular proposal of the present invention, the movement of the head yarn guide does not change in the plane where the inlet angle β of the take-up material to the yarn guide unit is laterally oriented towards the traverse axis of the traverse yarn guide, especially. Changes in the inlet angle β of +/- 5.0 ° or +/- 2.0 ° or +/- 1.0 ° or +/- 0.5 ° can still be included.

There are various possibilities for how to bring about the movement of the head thread guide. In the case of the deformations included in the present invention, the head thread guide is movable via the actuator, and the movement controlled by the actuator occurs in connection with the compensatory movement. To give only a few examples not limiting the invention, the diameter of the roll can be detected directly or indirectly using a sensor. For example, the sensor can detect the diameter of the winding through distance measurement, corrosive ring, and the like. It is also possible to indirectly detect the diameter of the winding by measuring the movement of the yarn guide unit as a result of the compensatory movement. It is also possible to indirectly detect the diameter of the winding by measuring the length of the wound winding material from which the diameter of the winding can be calculated. To give just one further example, the diameter of the winding can be indirectly inferred from the degree of movement of the traverse yarn guide, especially the number of strokes performed. Another possibility for detecting the diameter of the winding is to calculate it from the spindle speed and / or the speed of the take-up material. In that way, for example, from the integral of the speed of the take-up material (which can also be calculated from the process of spindle speed), the length of the take-up material to be wound up can be calculated, and from there again. The winding diameter can be determined based on the characteristic map or function dependence. When there is a corresponding signal with respect to the current diameter of the winding, the control unit can be used to drive the actuator, which moves the head yarn guide to the required degree.

A particularly simple but reliable possibility for bringing about head thread guide movement is the mechanical coupling between the compensatory movement of the thread guide unit and the movement of the head thread guide, so passive measures are taken here. .. In the simplest case, the yarn guide unit is mechanically coupled to the head yarn guide, even via a coupling means such as a coupling strut, or optionally through a gear connection, whereby the compensatory movement of the yarn guide unit is coupled. It is converted into the motion of the head thread guide through the kinetics of the gear coupling located between the strut or the head thread guide and the thread guide unit.

For example, as is known from various embodiments of the prior art, any traverse yarn guide can be used in the yarn guide unit. The winder of the present invention preferably uses a traverse yarn guide that slides and guides and / or deflects the winding material.

The length of the take-up material between the head yarn guide and the traverse yarn guide may vary within the framework of the present invention. In the proposal of the present invention, this length is at least 300 mm (for example, 350 mm or more, 400 mm or more, 450 mm or more, 500 mm or more, or 600 mm or more). Choosing such a length results in the distribution triangle also having a corresponding length, which can cause a change in the tension of the take-up material, take-up between the head yarn guide and the traverse yarn guide. Since the change in material length is relatively small, the use of compensation brackets can be omitted in some cases. On the other hand, when the length of the take-up material between the head yarn guide and the traverse yarn guide is so long, the deflection angle of the take-up material is also reduced in the area of the traverse yarn guide, thereby reducing the load on the take-up material. Will be done.

Basically, as explained at the beginning, the head yarn guide on the one hand and the yarn guide unit on the other hand can have any degree of freedom. In the proposal of the present invention, the thread guide unit and the head thread guide are guided in a translational manner, respectively, and the translational degrees of freedom of the thread guide unit and the head thread guide are oriented in parallel with each other. Here, preferably, the movement of the yarn guide unit on the one hand and the movement of the head yarn guide on the other hand are synchronized with the same amplitude along parallel degrees of freedom. For example, a head yarn guide is located in the lower end region of the winder, which can be guided horizontally and translationally using the guide. In this case, the yarn guide unit can be arranged in the upper end region of the frame of the winder, also with horizontal translational degrees of freedom. Thus, even with the small size of the winder, sufficient length of the take-up material between the head yarn guide and the traverse yarn guide can be assured with the advantages described above and here relevant. ..

Hereinafter, the present invention will be further explained and described based on the preferred embodiment illustrated.

FIG. 1 shows the winder in a three-dimensional view from diagonally above the front. FIG. 2 shows the winder of FIG. 1 in a front view. FIG. 3 shows the winder of FIGS. 1 and 2 in a front view, in which the frame is shown partially divided so that the connecting strut between the yarn guide unit and the head yarn guide can be seen. FIG. 4 shows the winders of FIGS. 1 to 3 in a side view. FIG. 5 shows the details of the front view of the winder of FIGS. 1 to 4 in the contact area of the yarn guide unit with the winding.

FIG. 1 shows a three-dimensional view of the winder 1. The winder 1 includes a frame 2 that can be formed of a cover plate, a housing, a frame, and the like. The frame 2 is held and / or guided by the essential members of the winder 1 listed below.

The winder 1 includes a rotary spindle 3 oriented parallel to the y-axis, here fixedly arranged. The thread guide unit 4 extends parallel to the spindle 3 and in the y-axis direction. The thread guide unit 4 is movably supported by the frame 2 via a guide 5 that defines a horizontal degree of freedom 6 here. The thread guide unit 4 has a pressing means 7 which is a pressing roller 8 here, and the pressing roller 8 is rotatably supported on the substrate of the thread guide unit 4 in parallel with the y-axis. Since the thread guide unit 4 is applied in the direction of the spindle 3 along the degree of freedom 6 via a suitable actuator or weight force not shown here, the thread guide unit 4 is via the pressing roller 8. It is supported by the outer surface of the winding created on the spindle 3 at a predetermined pressure. The thread guide unit 4 includes a traverse thread guide 9, which reciprocates in parallel to the y-axis by the traverse motion 10.

The take-up material 11 is provided, for example, over a continuous or discontinuous manufacturing process, the yarn guide unit 4, here the traverse yarn guide 9, the inlet roller 12, the deflection roller 13, and here the head yarn guide roller. It is supplied via the head yarn guide 14 formed as 15. There are no other guide elements between the head yarn guide 14 and the yarn guide unit 4 through which the winding material 11 is guided or deflected. A distribution triangle 16 having a total deflection angle α is set between the head thread guide 14 and the thread guide unit 4 (see FIG. 4), where the head thread guide 14 defines the vertices 17 of the distribution triangle 16 and is of the distribution triangle 16. The length corresponds to the distance 22 between the head thread guide 14 and the traverse thread guide 9. The head yarn guide 14 is guided here to the frame 2 via a guide 18 having translational and horizontal degrees of freedom 19.

In the figure, the x-axis indicates a horizontal direction oriented parallel to degrees of freedom 6 and 19 in the illustrated embodiment. The y-axis is oriented parallel to the longitudinal axis and / or rotation axis of the spindle 3. Further, the thread guide unit 4 extends in the y-axis direction, the traverse motion 10 of the traverse thread guide 9 is oriented parallel to the y-axis, and the pressurizing roller 8 rotates about the y-axis. Finally, the z-axis indicates the vertical axis of the wind turbine 1. The inlet angle β represents the angle of the take-up material 11 on the xz plane with respect to the z axis.

FIG. 2 shows a winder at the start of the winding process, i.e., when winding on the spindle 3 begins. At the beginning of the take-up process, the yarn guide unit 4 is positioned in the direction of 6 degrees of freedom, which has a minimum radial distance from the longitudinal axis of the spindle 3 and the axis of rotation. In the process of winding, the diameter of the winding increases, and as a result, the yarn guide unit 4 gradually moves away from the longitudinal axis and / or the axis of rotation of the spindle 3 by the compensatory motion 23 along the degree of freedom 6. .. Unlike the embodiment of the present invention, when the head thread guide 14 is fixedly arranged on the frame 2, the compensating motion 23 of the thread guide unit 4 changes the inlet angle β (illustrated embodiment example). In the case of: decrease), which is not desirable. In the present invention, the movement of the head thread guide 14 along the degree of freedom 19 is brought about, and the degree of movement of the head thread guide 14 corresponds to the degree of movement of the thread guide unit 4. Regardless of the winding diameter and the compensatory motion 23, this measure allows the inlet angle β to remain constant throughout the winding process. As a result, the shape, particularly the length of the distribution triangle 16 between the head thread guide 14 and the thread guide unit 4, does not change with the compensating operation 23.

The coupling between the motion of the thread guide unit 4 and the motion of the head thread guide 14 is formed here as a coupling strut 21 that firmly couples the thread guide unit 4 to the head thread guide 14 in the illustrated embodiment. This is done via the mechanical coupling means 20 (see FIG. 3). In this case, the coupling struts 21 preferably extend inside the frame or housing 2, so that they are not visible from the outside and are covered by the housing wall.

In FIG. 5, it can be seen that, in a possible form, the traverse yarn guide 9 is formed in a plate shape, and in this case, the traverse yarn guide 9 has, for example, a U-shaped recess through which the take-up material 11 passes. Then, at the center of the distribution triangle 16, the take-up material 11 passes linearly through the U-shaped recess without deflection, and the deflection is then U of the traverse yarn guide 9 due to the deviation from the center position. It is done through the side leg of the U, and as the distance from the center position increases, a stronger deflection occurs through this side leg of the U. Here, since the plate-shaped traverse thread guide 9 is oriented perpendicular to the inlet direction of the take-up material 11, the traverse thread guide 9 and the extending surface of the U-shaped recess also have the inlet angle β as well. Is inclined with respect to the xy plane.

Embodiments of the invention provide the following (alternative or cumulative) differences and advantages, especially over prior art known solutions using the fixed head yarn guide 14.

a) Since the inlet angle β does not change, the contact condition of the take-up material 11 with the head yarn guide 14 is independent of the compensating motion 23 and the diameter of the spool winding.

b) When the head thread guide 14 is formed as the head thread guide roller 15, the embodiment of the present invention changes to the extent that the winding angle of the head thread guide roller 15 does not change or is reduced by the compensating motion 23. It also brings the result. (In particular, when the take-up material 11 swells on the head yarn guide roller 15 in parallel with the compensating motion 23, a winding angle that does not change due to the correction operation 23 occurs, whereas another take-up direction of the take-up material 11 occurs. In the case of, the winding angle may change due to the compensatory movement 23 on the head yarn guide roller 15.)

c) Furthermore, the conditions under which the take-up material 11 is supplied to the yarn guide unit 4, and in particular the traverse yarn guide 9, are not relevant to the compensatory motion 23 and therefore to the diameter of the winding being constructed. For example, when the winding material 11 is pulled more strongly into the base of the U-shaped recess of the traverse thread guide 9 by changing the inlet angle β by the measures of the present invention (expansion of the inlet angle β), thereby. The deflection angle of the take-up material 11 can also be prevented from expanding in the region of the U-shaped recess of the traverse yarn guide 9. Due to the reduced inlet angle β by the measures of the present invention, when the take-up material 11 enters the traverse thread guide 9, the take-up material 11 is under the modified angle, the side legs of the U-shaped recess. It can also be prevented from being pulled slightly upwards from.

d) The distance 22 of the head yarn guide 14 from the traverse yarn guide 9 (see FIG. 2) is at least 300 mm. Due to the relatively large distance of the head yarn guide 14 from the traverse yarn guide 9, the length of the take-up material 11 between the head yarn guide 14 and the traverse yarn guide 9 changes only slightly during the stroke of the traverse motion 10. Therefore, in some cases, the compensation measure 23 such as the use of the compensation bracket becomes unnecessary. Here, the distance 22 correlates with the length of the distribution triangle 16.

e) In the present invention, avoidance or reduction of quality deterioration of the winding material 11 as a result of the contact conditions of the winding material 11 changing over the winding process, and improvement of the winding quality for the winding machine. Occurs. In this case, the inlet angle β changes over the winding process with the modified overall traverse angle α of the distribution triangle 16, optionally consequent here.

f) In the present invention, even when the winding material 11 is not wound and only the guide of the winding material 11 is performed parallel to the longitudinal axis and / or the rotation axis of the spindle 3, the traverse yarn guide 9 may be used. Can be used. In this embodiment, the take-up material 11 can be protected as a result of a reduction in bending load due to omission of winding.

In the present invention, in the embodiment in which the movement of the head thread guide 14 is related only to the compensatory movement 23 of the thread guide unit 4, the movement of the head thread guide 14 is related to the compensatory movement 23 of the thread guide unit 4. Also includes at least one other drive scale related embodiment.

Further, the present invention includes an embodiment in which the movement of the head thread guide 14 is coupled to the movement of the thread guide unit 4 only over the partial stroke of the compensatory movement 23, not over the entire stroke. The coupling of the motion of the head thread guide 14 with the motion of the thread guide unit 4 can be made here via any linear or non-linear association.

As such, the present invention includes embodiments in which the movement of the head yarn guide 14 occurs not only in the context of the movement of the yarn guide unit 4, but also for additional purposes. For example, when the head yarn guide 14 moves via an actuator, the motion of the head yarn guide 14 can also be used to at least temporarily control or adjust the tension of the take-up material 11. To give only another non-limiting example, the movement of the head yarn guide 14 supports or enables gripping or cutting of the take-up material 11, for example, or because of this special driving condition. It can be done at the beginning of the winding process, at the end of the winding process, or to replace the spool to provide an advantageous configuration of the winder 1.
